Control a slider with JSON value range

[JRHall]

I have a JSON file with a range of values from 416 - 423 which I want to use as the min and max of a slider, but still have the slider run from 0-100%.

Basically, I want the slider to read 416 and return 0 and read 423 and return 100.

Any ideas welcome. Thanks

Assuming variable  n has the json value, you could do something like this:

n = // (your json value)

linear(n,416,423,0,100)

Yes, as Dan suggested, you need to use the linear() expression.

See this tutorial for more details of how linear() can be useful for json data:

Thanks Dan and Mathias,

I will test this later today and let you know if it does the job

Thanks
